GEO600 beam splitter thermal compensation system: new design and commissioning
Séverin Nadji, Holger Wittel, Nikhil Mukund +8
Gravitational waves have revolutionised the field of astronomy by providing scientists with a new way to observe the universe and gain a better understanding of exotic objects like…
Characterization and evasion of backscattered light in the squeezed-light enhanced gravitational wave interferometer GEO 600
Fabio Bergamin, James Lough, Emil Schreiber +15
Squeezed light is injected into the dark port of gravitational wave interferometers, in order to reduce the quantum noise. A fraction of the interferometer output light can reach t…
First demonstration of neural sensing and control in a kilometer-scale gravitational wave observatory
Nikhil Mukund, James Lough, Aparna Bisht +9
Suspended optics in gravitational wave (GW) observatories are susceptible to alignment perturbations, particularly slow drifts over time, due to variations in temperature and seism…
Direct limits for scalar field dark matter from a gravitational-wave detector
Sander M. Vermeulen, Philip Relton, Hartmut Grote +20
The nature of dark matter remains unknown to date; several candidate particles are being considered in a dynamically changing research landscape. Scalar field dark matter is a prom…
First demonstration of 6 dB quantum noise reduction in a kilometer scale gravitational wave observatory
James Lough, Emil Schreiber, Fabio Bergamin +14
Photon shot noise, arising from the quantum-mechanical nature of the light, currently limits the sensitivity of all the gravitational wave observatories at frequencies above one ki…
Bilinear noise subtraction at the GEO 600 observatory
Nikhil Mukund, James Lough, Christoph Affeldt +8
Longitudinal control signals used to keep gravitational wave detectors at a stable operating point are often affected by modulations from test mass misalignments leading to an elev…
